• Emissions test failures caused by a worn oxygen sensor

Installation Notes and Tips

Verify the sensor position before installation, since this application covers upstream left, upstream right, and upstream locations depending on vehicle and emissions package. Confirm the connector routing and harness length match the original layout before tightening the threaded sensor into place. Always compare the old sensor’s connector style, thread size, and wire count to the replacement part before installation.
